emacs already does everything-- no tool is ever going to do more than emacs (before you say it, i know this isn't literally true.)

so when i already have a tool that does everything (actually multiple tools), what might i want in a different tool? to extend the metaphor of a tool: i'd want a tool that feels better in my hand, or a tool that does a specific job very well, or a tool that can fit better into tight and awkward spaces, or a tool that works by a different principle, or just a more beautiful specimen of the same tool that does everything. or maybe i'd want a different tool for one of the many reasons i'm sure i haven't thought of.

just some stray thoughts, nothing original, but it makes me realize that i'm always looking for tools that work on a different principle to the ones i've got, and that's never occurred to me before now.
